Recently I bought a 580SC, really happy with it too.
However, I realized there are more bottlenecks in a system than vid card alone, so I decided to renew my rig.
This time I wanted a GTX590.
However, in my country, an EVGA 590 was not to be found, so I had to settle for a Gainward 590 (so sorry for that EVGA) I hope for forgivness among the members
I reach to you because I have never seen so much expertice in the graphics dept than here.
OK, here it goes.
In game (Front Mission Evolved) I experienced from first visit, some strange stuff.
In some light conditions, heavy flickering, really annoying too.
Transparent structures appeared, like see through walls not really there.
Structures below the floor became visible.
Kinda light ray's shining through the invoronment.
Is this what you call "Artifacts"? (I'm non english)
I have tried this:
Clean driver install (Thanks maniac) 285.62 and yesterday 290.36
Toggled through both 59 and 60Mhz in 1920X1080 with and without MSIAA X2 and X4
No temp issue, this card really runs cool

prox 40-50celcius (in game)
All in game measurements are normal, no peaks, no dip's. (MSI Aftergurner)
Stock clocking.
No CPU issues, stable and cool
VSYNC on&off
All ingame vid settings has been adjusted to low, then adjusted up again in steps.
Haven't tried other games, but my present game ran smooth on the 580 card.
I do not have any FPS measurements. (How do you guy's measure FPS?)
So guy's, any idea what this might be?
Any feedback would be most appreciated, I'm kinda stuck here.
